To @ZZ whom t 11i/tty concern:

Be it known that I, WILL K. MARTIN, a citizen of the United States, residing at Viaslr.l

ington, in the District of Columbia, have invented certain new and useful Improvements in VindoW-Shade Supports; and I do hereby declare the followingto be a full,

, clear, and exact description of theinvention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in window-shade supports, and has particular reference to a `shade-support Which is capable of adjustment for setting the shade at any desired angle.

It consists of parallel arms pivotally supported by a Window-casing, movable brackets carried thereby for supporting a shadepole, and means for adjusting said brackets longitudinally of said arms.

It also consists of arms pivoted at4 their inner ends to the verticalgwalls of a Window# casing, a housing extending longitudinally of each of said arms, a bracket slidable within each of said housings and each adapted to support one end of a shade-pole, and a flexible cable secured to each of said brackets and adapted to be operated for moving the same longitudinally of said housings. v

It further consists of parallel arms carried by the sides of a window-casing and free to swing toward the Window in a horizontal plane, housings carried by said arms, longitudinal slots formed in said housings, ablock slidable Within each of said housings and having a perforated flange extending through said slot, a bracket engaging each of said perforated flanges, each bracket being adapted to support one end of a curtain or shade pole, and means operable from the lower portion of the window for sliding said blocks longitudinally of said housings.

It still furthur consists of certain other novel constructions, combinations, and arrangements of part-s, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure-1 represents a front elevation of a window having applied a window-shade support embodying the features of the present invention.

Fig. 2 represents a longitudinal vertical section on line 2 2 of Fig. l, one of the supportingarms being thereby shown in side elevation. Fig. 3 represents a transverse horizontal section on line 3 3 of Fig. l, the shade-support being shown in top plan. Fig. i represents aview in side elevation of one of the supporting-arms, the front Wall of the housing being cut away to more clearly illustrate the elements. Fig. 5 represents an enlarged detail perspective View of the sliding block and its pole-supporting bracket, and Fig. 6 represcnts a detail top plan view of a portion of a curtain-pole with the head of its axis in engagementwith its bracket.

In the positioning of window-shades, par-` ticularly in rooms occupied by a large num- 'ber of persons, it has been found extremely difficult to so arrange the saine as to give a proper or desirable proportion of light to all of the said occupants, and to accomplish this result in the easiest possible manner I provide, asY seen byreference to the drawings,

,suitable horizontally-disposed arms, as 1 l, which are adapted-to be pivoted at any suitable point, preferably to the casing of the Window, by means of any suitable pintles, as 2 2, nding bearings in anypreferred sockets, as 3 3; but of course any form of hinges desired may be employed.

Arranged longitudinally of each Ofarms l and secured thereto inv any suitable manner is a housing, asd, which is provided with a longitudinal slot, as 5, in which slot operates the ange 7 of a suitable block, as 6, which blockV is adapted to slide longitudinally with-y in said housing. Eyes, as 8 and 9, are formed upon or secured to the ends of block 6 andare adapted yto receive the ends of a flexible chain or cable, as V10, which chain or cable passes outsuitable apertures at the ends of housings 4, one part of the said cable passing abolita suitable antifriction-pulley, as ll, near the outer end of arm l, the end corresponding to that part being secured `to eye 8 of block 6, and after passing said pulley 1l it passes about a second pulley, as 12, and is f thendirected downwardly and about a similar pulley, as 13, andk upwardly again about a pulley, as 14, and is finally secured at its end to eye 9, whereby an endless-cable effect is produced, and a pull upon cable l0 at any point of its length will eect the moving of ICO block 6 in a direction corresponding with the direction of the pull. Flange 7 is preferably perforated to receive the shank 16 of bracket 15, whereby said bracket is free to rotate; but of course it will be seen that any preferred form of pivotal bracket may be employed in conjunction with block 6. Bracket 15 may be provided with a slot for the reception of the squared end of the axis of the common form of shade-pole provided with the well-known spring-operating mechanism, or it may be provided with a circular aperture at the inner end of the slot for forming a bearing for the cylindrical axis of the said pole, one of each form being employed for supporting each curtain-pole, as is common. The axes, as 1717, of shadepole 18 are formed one polygonal and the other cylindrical, as is common, and a head, as 19, larger than the slot in said bracket is formed upon each of said axes, whereby the same must be applied to the said brackets by a lateral movement and cannot be removed longitudinally.

In operation, the parts being in the position shown in full lines in Fig. 3, a pull upon cable 10 at one side of the window will bring the parts to the position shown in dotted lines in said figure, with the pole 18 setting at an acute angle to each of the arms 1, the arm 1 carrying the moved end of the pole having moved inwardly sufficiently to compensate for the altered position of the said pole. A similar pull upon the cable 10 upon the opposite side of the window would bring the other end of pole 18 to a corresponding position upon its arm 1 to that occupied by the first-mentioned end, whereby the arms would be caused to again assume their parallelism. It will be seen that the curtain may be moved outwardly entirely to the end of housings 4 by simply pulling equally upon the cables 10, and to return the curtain to its normal position requires only a reverse pull upon the said cables.

It will be readily seen that many advantages accrue from the construction of the va? rious features of my present invention, the chief one of which is of course the ready adjustment of the shade or curtain to any desired position or angle, and many minor advantages will be apparent which4 do not need mentioning. One other prominent advantage lies in the fact that arms 1 may be readily applied to any Window-frame, whether in a house or upon the market and in condition for being placed in a house. The present construction is particularly Well adapted for being placed upon Window-frames which are upon the market, owing to the factthat the said arms 1 may when not prevented by the interposition of pole 18 -be folded inwardly upon themselves, and the said Window-casing will occupy no more room when provided with the said arms and the remaining features of my present invention, except the said pole, than if the said improvements were not present.

[ Although I have described and shown in detail one particular embodiment of the present invention, yet I do not wish to be understood as limiting myself to the exact form of structure specified, but shall feel at liberty to deviate from the exact size, shape, and minor details of the present parts Within the spirit and scope of my invention.

It will of course be apparent that arms 1 will'be pivoted to the sides of the windowcasing at a sucient distance from the outer edge thereof to present enough of the side of each of the said arms to its respective side of the said casing to prevent the said arms from being pivoted outwardly beyond a right angle to the vertical plane of the respective sides of the window-casing, although the said arms are free to be swung inwardly.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
